2AgNO3 + H2SO4 --> Ag2SO4 + 2HNO3Brown precipitate is formed.
NaCl + H2SO4
No reaction.
Ag2CO3 + H2SO4 ---> Ag2SO4 + CO2 + H2O
Ag2CO3 dissolves and colourless bubbles are evolved.
Also, brown precipitate is formed.
NaCl + HNO3
No reaction.
NaCl + HCl
No reaction.
NaNO3 + HCl
No reaction.
AgCl + HCl
No reaction.
Ag2CO3 + 2HCl ---> 2AgCl + CO2 + H2O
Ag2CO3 dissolves and colourless bubbles are evolved.
Also a white precipitate is formed.
